Description

Technical Field

[0001] This utility model relates to the field of extruder head technology, specifically an adjustable extruder head for steel-plastic composite pipe production. Background Technology

[0002] In the production of steel-plastic composite pipes, the extruder head is a crucial piece of equipment. Its performance directly affects the molding quality and production efficiency of the pipes. Traditional adjustable extruder heads often have a highly integrated structure, lacking convenient internal maintenance design. This requires extensive disassembly of the entire extruder head, consuming significant time and manpower. Furthermore, it makes internal maintenance of the extruded pipe difficult, allowing potential minor problems to gradually worsen and eventually lead to more serious equipment failures, production interruptions, and substantial economic losses for the company. During the extrusion molding process of steel-plastic composite pipes, a specific temperature range is required to exhibit good fluidity, thereby uniformly and stably coating the steel pipe skeleton and achieving a tight composite between the two. When the temperature is too low, the viscosity of the plastic melt increases, the fluidity deteriorates, and it is difficult to extrude evenly and fully fill the gaps and surfaces of the steel pipe skeleton. This results in uneven plastic layer thickness in the composite pipe, with defects such as localized thinness or voids, which seriously affect the overall performance of the pipe. Utility Model Content

[0003] This invention provides an adjustable extruder head for the production of steel-plastic composite pipes, which solves the problems of existing equipment being difficult to maintain, leading to more serious equipment failures, and lacking constant temperature control, resulting in uneven plastic layer thickness in the composite pipe and reduced production quality.

[0004] This utility model provides the following technical solution: an adjustable extruder head for producing steel-plastic composite pipes, including a base plate and an extruder disposed on one side of the top surface of the base plate, and an extrusion head disposed on one side of the extruder. A maintenance mechanism is fixedly connected to the periphery of the end of the extrusion head. The maintenance mechanism includes a fixing plate, a fixing hydraulic rod, a top block, a limiting post, and a limiting plate. An extrusion tube is installed on one side of the extrusion head. A temperature control mechanism is installed inside the extrusion tube. The temperature control mechanism includes a heating grid, a temperature sensor, and a temperature controller.

[0005] As a preferred embodiment of this utility model, the fixing plate is fixedly connected to the periphery of the end of the extrusion head, a fixing hydraulic rod is fixedly connected to one side of the top of the fixing plate, a top block is fixedly connected to the top of the fixing hydraulic rod, a limit post is fixedly connected to one end of the top block, and the limit plate penetrates through the outside of the limit post.

[0006] As a preferred embodiment of this utility model, the heating mesh is installed inside the extrusion tube, and a temperature sensor is fixedly connected to the outside of the extrusion tube. The end of the temperature sensor is electrically connected to a temperature controller via a power line.

[0007] As a preferred embodiment of this utility model, the temperature controller is fixedly connected to one edge of the top surface of the base plate, and the end of the temperature controller is electrically connected to a PLC controller via a power cord.

[0008] As a preferred embodiment of this utility model, a partition is fixedly connected to the inner side of the extrusion tube, and the inner side of the partition is fixedly connected to the outer side of the heating mesh.

[0009] As a preferred embodiment of this utility model, a heat-conducting layer is fixedly connected to the inner side of the heating mesh, and an inner protective layer is fixedly connected to the inner side of the heat-conducting layer.

[0010] As a preferred embodiment of this utility model, a fixed plate is fixedly connected to the end of the extrusion tube, and a telescopic hydraulic rod is fixedly connected to one side of the fixed plate. The end of the telescopic hydraulic rod is fixedly connected to the inside of the extrusion head.

[0011] As a preferred technical solution of this utility model, a limiting hole is provided inside the bottom end of the fixing plate, the inside of the limiting hole extends through the outside of the end of the limiting post, and a fixing nut is threadedly connected to the outside of the limiting post.

[0012] Compared with the prior art, this utility model provides an adjustable extruder head for the production of steel-plastic composite pipes, which has the following advantages: The adjustable extruder head used in the production of steel-plastic composite pipes features a maintenance mechanism. When the device is in use, a fixing plate is installed on the outside of the extrusion head's end. A fixing hydraulic rod is installed on one side of the fixing plate, and a top block is installed at the top of the fixing hydraulic rod. A limiting post is installed at one end of the top block. When the extrusion head and extrusion tube extend and retract via the internal telescopic hydraulic rod to separate, and then retract and reassemble after maintenance, the limiting plate at the end of the extrusion tube will fit against the fixing plate, and the limiting post will pass through the limiting hole inside the limiting plate. A fixing nut is then tightened onto the outside of the limiting post's end for further reinforcement. This facilitates disassembly for internal inspection and maintenance, preventing the difficulty of inspecting the inside of the extrusion tube. This avoids the possibility that small potential problems could gradually worsen and eventually lead to more serious equipment failures, production interruptions, and significant economic losses.

[0013] The adjustable extruder head used in the production of this steel-plastic composite pipe features a constant temperature mechanism. A heating mesh is installed inside the extruded tube during operation. This heating mesh is connected to a temperature sensor, which in turn is connected to a temperature controller. The combined use of the temperature controller and temperature sensor allows for stable control of the extruded tube's heating temperature, maintaining a stable temperature. This prevents the plastic melt from becoming too cold, which increases viscosity, reduces fluidity, and makes it difficult to evenly extrude and fully fill the gaps and surface of the steel pipe skeleton. Such conditions can lead to uneven plastic layer thickness, localized thinness, or voids, severely affecting the overall performance of the pipe. Attached Figure Description

[0021] In this embodiment, a heating mesh 601 is installed inside the extrusion tube 5. The heating mesh 601 is connected to a temperature sensor 602, which is then connected to a temperature controller 603. The temperature controller 603 and the temperature sensor 602 work together to stably control the heating temperature of the extrusion tube 5.

[0030] In summary, the adjustable extruder head used in the production of this steel-plastic composite pipe, through the setting of the maintenance mechanism 4, facilitates disassembly for internal inspection and maintenance, avoiding the difficulty of inspecting the inside of the extrusion tube 5. This prevents potential minor problems from gradually worsening and ultimately leading to more serious equipment failures, production interruptions, and significant economic losses. Furthermore, the constant temperature mechanism 6 maintains the temperature of the extrusion tube 5, preventing excessively low temperatures that could increase the viscosity of the plastic melt, reduce its fluidity, and hinder uniform extrusion and filling of the gaps and surface of the steel pipe skeleton. Such conditions would result in uneven plastic layer thickness in the composite pipe, with defects such as localized thinness or voids, severely impacting the overall performance of the pipe.
